Method and Apparatus for Applying Autonomous Denial in Wireless Communication

1. A method for applying, by a user equipment (UE), autonomous denial in a wireless communication system, where the UE is served by a primary cell (PCell) and a secondary cell (SCell) the method comprising: receiving a Radio Resource Control (RRC) connection reconfiguration message from a network, wherein the RRC connection reconfiguration message includes a first denial rate for the PCell, a second denial rate for the SCell, and a third denial rate for the UE; determining whether to perform an autonomous denial in the PCell; when it is determined that autonomous denial is performed in the PCell, counting a number of aggregated denials of uplink (UL) subframes in the PCell over a validity period; denying scheduled UL transmission at a current subframe when the number of aggregated denials of UL subframes in the PCell is less than the first denial rate and when a total number of aggregated denials of UL subframes for the UE is less than the third denial rate; determining whether to perform an autonomous denial in the SCell; when it is determined that autonomous denial is performed in the SCell, counting a number of aggregated denials of uplink (UL) subframes in the SCell over the validity period; and denying scheduled UL transmission at the current subframe when the number of aggregated denials of UL subframes in the SCell is less than the second denial rate and when the total number of aggregated denials of UL subframes for the UE is less than the third denial rate.

2. The method of claim 1 , wherein the first or second denial rate is the maximum aggregate number of assigned UL subframes for which the UE is allowed to deny the scheduled UL transmission in the PCell or SCell.

3. A user equipment (UE) in a wireless communication system, the UE comprising: a radio frequency (RF) unit that transmits or receives a radio signal; and a processor, coupled to the RF unit, that: controls the RF unit to receive a Radio Resource Control, RRC, connection reconfiguration message from a network, wherein the RRC connection reconfiguration message includes a first denial rate for the PCell, a second denial rate for the SCell, and a third denial rate for the UE; determines whether to perform an autonomous denial in the PCell; counts a number of aggregated denials of uplink (UL) subframes in the PCell over a validity period when it is determined that autonomous denial is performed in the PCell; and denies scheduled UL transmission at a current subframe when the number of aggregated denials of UL subframes in the PCell is less than the first denial rate and when a total number of aggregated denials of UL subframes for the UE is less than the third denial rate; determines whether to perform an autonomous denial in the SCell; counts a number of aggregated denials of uplink (UL) subframes in the SCell over the validity period when it is determined that autonomous denial is performed in the SCell; and denies scheduled UL transmission at the current subframe when the number of aggregated denials of UL subframes in the SCell is less than the second denial rate and when the total number of aggregated denials of UL subframes for the UE is less than the third denial rate.

4. The UE of claim 3 , wherein the first or second denial rate is the maximum aggregate number of assigned UL subframes for which the UE is allowed to deny the scheduled UL transmission in the PCell or SCell.
